Steve Wozniak, co-founder of Apple, was treated to a surprise birthday party Aug. 1 in San Francisco. About 400 people gathered at the Yerba Buena Center for the Performing Arts to honor the man known to most people as "Woz," who turns 62 Aug. 11. The party was hosted by Fusion-io, a flash storage memory company Wozniak joined in 2009 as chief scientist. He was brought to the venue under the ruse that the event was a Fusion-io product launch. Woz was showered with confetti and praise for his innovative leadership at Apple, which he founded along with the late Steve Jobs in 1976. Woz contributed his computer engineering skills to the technology inside Apple PCs and other products, while Jobs contributed his vision of product design and marketing. Woz was lauded for his philanthropic work and teased about his love of the video game Tetris–guests received their own Tetris games in their swag bags—and his appearance on the ABC network reality TV show "Dancing with the Stars" in 2009. When appearing onstage at the event, the portly Woz quipped, "I hope you don't want me to do any ballet stuff."
